The material of the valve is different from that of the pipeline; could everyone help me analyze this?

The pipe material is 12Cr1MoVG, while the valve material is 12Cr1MoV. Will there be any issues if they are welded together without using any fittings?

There should be no problem; ‘g’ refers to steel used for boilers, and 12Cr1MoVg is simply a subtype of 12Cr1MoV, with the same chemical composition.

There’s no problem with this; it can be welded directly, just as the person above said

But I checked online, and it says that 12Cr1MoVG is obtained by adding several different elements to the 12Cr1MoV material
